Title: Improvements in and relating to the Manufacture of Cocoa Paste
Inventor: NEUMANN FRIEDRICH ERNST FERDIN
Filed: 1903-04-01
Granted: 1904-02-04
Abstract: 7595. Neumann, F. E. F. April 1. Cocoa.-In making cocoa paste, the cocoa beans are placed in a heated hopper d, and fed by a roller f between one or more pairs of roughened rotating rollers a arranged one above the other, one or more rollers e at the side of the lowest pair of rollers a removing the paste from these rollers. Steam, hot-water, or other heating-passages d<1> formed in the walls of the hopper, and also transversely or longitudinally across the same, are connected by ribs or plates d<2> to ensure a better distribution of the heat. The pulverized and melted material is removed from the first pair of rollers a by scrapers c, and falls upon the next pair of rollers, the paste being finally removed from the lateral roller e by a scraper c. Heating- passages b are provided for heating the rollers, if desired. Or the beans may be supplied to the hopper d in a heated state. The Provisional Specification states that the lateral rollers may be dispensed with.

Patent GB-190310755-A (GB)
Title: Improvements in Automatic Electrical Alarm Apparatus.
Inventor: LASSEN HERMANN RUDOLPH
Filed: 1903-05-12
Granted: 1903-06-18
Abstract: 10,755. Lassen, H. R. May 12. Alarms, burglar and like.-Relates to a portable apparatus in which an electric bell is sounded in case of burglary. Fig. 1 shows a front view, and Fig. 2 a sectional view of the apparatus. Strips of metal c, electrically connected by a wire, are fixed, one at the top, and one at the bottom of a recess b, cut in a plate of insulating material a. A metal spring d is fixed in the recess b so that its ends are just out of contact with the strips c. A string passes through the insulating block a, and suspends a weight e. An electric bell circuit is connected to the spring d, and to the strips c, so that if the string suspending the weight is tightened in opening a door or the like, the weight rises, and makes contact between the spring d and strips c, thus completing the circuit, and sounding the bell. If the string is cut, the weight falls, and again completes the circuit at the lower strip c.

Title: A New or Improved Variable Speed or Feed Gear.
Inventor: KNIGHT STEPHEN
Filed: 1903-05-19
Granted: 1904-03-31
Abstract: 11,422. Knight, S., and Campbell, A. May 19. Lathes.-In a variable - speed or feed gear for use on motor vehicles and screw-cutting lathes &c., drum d, Figs. 1 and 2, has external teeth d<2> gearing with a pinion d' on the driven shaft z, and internal ratchetteeth d<1> to engage with pivoted blocks k, k<1>, k<2> which are operated by means of toggle-links h, h<1>, i, i<1>, j, j<1>. One end of each of the links h, i, j is pivoted to the face of the bearing-support c<2> ; the central joints of each pair of links are connected respectively to arms g, g<1>, g<2> on a boss G<1> which is actuated by means of a disc a on a variable-throw crank b, to give the required motion to the togglelinks, which in turn operate the blocks k, k<1>, k<2> to bring them successively into gear with the ratchetteeth to rotate the drum d. The crank b, which is shaped as shown in Fig. 2, and is preferably of square section, receives motion from a belt-driven pulley m which is slotted to receive the end of the crank. The disc a fits the inclined part of the crank ; its eccentricity is varied by drawing the shaft b to the right by means of a worm t gearing with a wheel s which is screwed to the flange of a hollow rotating piece q<1> provided with a central screwed stem q. This screw engages an extension p of a disc o which is secured in a casing n. The flanged end b<3> of the shaft b enters the casing n, and is retained by a disc n<1>. A projection n<3> and rod n' prevent the casing n from rotating. A distance-piece y prevents lateral movement of the disc a. In a modified arrangement, the ratchetteeth in the drum d are replaced by spur-teeth, and the blocks k, k<1>, k<2> by pinions which are provided with clutch or free-wheel mechanism so that they drive in one direction and rotate idly in the opposite direction. If the gear is not required to be altered while in motion, the variable-throw crank may be dispensed with ; the disc a is then mounted on the face of a plate or pulley, or in the case of a lathe, it is fitted to the fixed headstock, the required eccentricity being obtained by means of screw mechanism.

Title: Improved Automatic Method of Shifting Tramway Points
Inventor: COOLEY HORATIO
Filed: 1903-08-08
Granted: 1904-07-14
Abstract: 17,264. Cooley, H. Aug. 8. Points and switches.-Relates to tramway points and consists in means for operating them from oncoming cars. Fig. 1 shows a plan, part of the cover-plate being removed, and Fig. 2 a sectional elevation of the mechanism which consists of a plate A pivoted at P and connected by the rod R to the lever D which is connected to the points to be operated. Two grooves G are formed in the upper face of the plate A which form a sector of a circle with the pivot P as centre and are continuous with the grooves g. The lower end portion of the plate A carries one or more wheels W which engage with one or more wheels W<1> carried by the pin S. A spring S' is fixed to the pin S so as to cause the wheel or wheels W<1> to press against the wheel or wheels W. The action of these two sets of wheels is to form a locking-arrangement for the points or the plate A, and also to prevent them from setting in any but the desired positions. If desired, the wheel or wheels W<1> may be attached to a straight spring instead of to the pin S as shown in Fig. 2. The plate A is operated by a lever depending from the car, which is guided into one of the grooves G by one of the grooves g, and, after having rotated the plate as desired, passes into another set of grooves in the plate H which gradually diminish in depth as shown by the broken line in Fig. 2.

Massage; light, treating diseases with.-Massage apparatus with means for directing rays of light on the parts of the body under treatment, consists of a transparent glass cylinder a, Fig. 2, which may be corrugated, rotatably mounted in a forked handle e, and containing an incandescent lamp f. A reflector i, fixed between the arms of the fork, directs the light on to the part of the body operated upon. The ends b, b<1 >of the cylinder are cemented in, and provided with, pivots c, c' supported in bearings in the ends of the handle. The lamp is carried by a holder fixed to the handle and passing through the hollow pivot c', the conducting-wires g passing through the handle, in which is arranged a switch operated by a button h for breaking the circuit ; or the lamp may revolve with the cylinder, the wires being connected by a conducting-disc revolving with the cylinder, and a contact spring fixed to the handle and bearing against the disc. A globular chamber may be used instead of a cylinder, and other sources of light instead of electricity. Fig. 3 shows a glass ball j free to revolve in a socket k, antifriction balls or studs l, and a screwed ring n, which may also carry balls or studs, keeping the ball in position. Two or more balls mounted in one handle may be used. Transparent coloured screens may be placed between the lamp and the part of the body operated upon, and it is preferred to make the fork and handle in two parts.

Title: Improved Roller Blind Shutter for Photographic Cameras.
Inventor: LANGE ADOLPH RICHARD
Filed: 1904-10-17
Granted: 1904-11-17
Abstract: 22,324. Lange, A. R. Oct. 17. Shutters. - In a roller-blind shutter, the adjustment of the exposure opening is effected by the same action that sets the shutter without the use of a separate handle, and, further, this adjustment may be made while the front of the camera is open. In Fig. 2, the blind a is shown attached to the two rollers b, c, the latter being controlled by a strong spring. The blind a contains an opening for the largest exposure, and just above this opening the bar i is attached to the blind. Another blind d on the spring roller e terminates with the metal barf, which carries two flat springs h by means of which it can grip the two straps forming the edges of the blind a. Initially, the bars i, f are in light-tight contact. The roller b is then turned and winds up the blind a, carrying with it the bars i,f. The barf will be stopped on reaching the projections l, but the bar i, being shorter, is carried on. In this way, the bars i, f are separated and an opening obtained of any size. On releasing the roller b, this opening is rapidly drawn across the lens and the exposure made. Near the end of its path, the bar f strikes the thin edge of the wedge m, which opens out the flat spring h and thus lessens its grip on the straps of the blind a. This permits the blind a to travel on till the bar i, which it carries, closes up on the bar f once more.
